5.2.13 Motion control linkage adjustment.
WARNING
POTENTIAL HAZARD
♦ Engine must be running and drive wheels must be turning
so motion control adjustment can be performed.
WHAT CAN HAPPEN
♦ Contact with moving parts or hot surfaces may cause
personal injury.
HOW TO AVOID THE HAZARD
♦ Keep fingers, hands, and clothing clear of rotating
components and hot surfaces.
CAUTION
POTENTIAL HAZARD
♦ Raising the mower deck for service or maintenance
relying solely on mechanical or hydraulic jacks could be
dangerous.
WHAT CAN HAPPEN
♦ The mechanical or hydraulic jacks may not be enough
support or may malfunction allowing the unit to fall, which
could cause injury.
HOW TO AVOID THE HAZARD
♦ DO NOT rely solely on mechanical or hydraulic jacks for
support. Use adequate jack stands or equivalent support.
a) This adjustment must be made with the drive wheels turning. First raise the
frame and block up so that drive wheels can rotate freely.
b) Disconnect the electrical connection from the seat wire harness from the main
harness. The electrical connection is below the seat hold up rod just above
the left wheel drive pump.
Temporarily install a jumper wire across the terminals in the connector of
the main wiring harness.
c) Run the unit at least 5 minutes with the drive levers at full forward speed to
bring hydraulic system oil up to operating temperature. Return the drive
levers to the neutral position.
d) Tilt seat forward.
e) Loosen lock nut from the ball joints at the pump end of the RH pump control
linkage (See Figure 19).
